Product details
Overview
R5F212BCSNLG#U0 from Renesas Electronics is a 16-bit R8C/Tiny Series MCU in the R8C/2B Group, featuring 128 KB flash program memory, 1 KB × 2 on-chip data flash, 7.5 KB RAM, and operation at up to 20 MHz (VCC = 3.0–5.5 V). It integrates 12-channel 10-bit A/D, dual 8-bit D/A converters, six timer modules (including three-phase PWM-capable Timer RD), LIN hardware interface, and UART/SSU/I²C serial interfaces. It targets embedded control in consumer audio equipment and office automation systems requiring low-power real-time processing.
For engineers reviewing the R5F212BCSNLG#U0 datasheet, R5F212BCSNLG#U0 pinout, R5F212BCSNLG#U0 application, or R5F212BCSNLG#U0 equivalent, key selection considerations include its 64-pin FLGA package (PTLG0064JA-A), -20°C to +85°C industrial temperature grade (N version), on-chip data flash endurance (10,000 erase/write cycles), and hardware LIN compliance using UART0 and Timer RA.
Technical Context
The R5F212BCSNLG#U0 implements the R8C/Tiny CPU core with 89 fundamental instructions and a dedicated 16×16→32-bit multiplier for efficient signal processing. Its clock system includes XIN/XOUT (up to 20 MHz), XCIN/XCOUT (32 kHz real-time clock), and programmable high-/low-speed on-chip oscillators with frequency adjustment.
Peripheral integration centers on deterministic real-time control: Timer RD supports reset-synchronous and complementary PWM for motor drive, while the LIN module offloads protocol handling from firmware. The 12-channel A/D converter includes sample-and-hold, and dual 8-bit D/A outputs support analog feedback loops without external DACs.
